We had to manually remove all details from the OEM server as below :
[oracle@oem01 bin]$ ./emcli login -username=sysman
Enter password :
Login successful
[oracle@oem01 bin]$ ./emcli delete_target -name=odw01.nyfps.net:3872 -type=oracle_emd -delete_monitored_targets -async
Target "odw01.nyfps.net:3872:oracle_emd" deleted successfully
After checking on OEM there was no reference to the odw01 server - removed the agent from the actual odw server itself.
[oracle@odw01 install]$ perl ./AgentDeinstall.pl -agentHome /u01/app/middleware/agent_13.2.0.0.0
Agent Oracle Home: /u01/app/middleware/agent_13.2.0.0.0
agentHome = /u01/app/middleware/agent_13.2.0.0.0
Agent installed in config modevalue of skip flag is false
NOTE: The agent base directory: /u01/app/middleware will be removed after successful deinstallation of agent home.
The command is /u01/app/middleware/agent_13.2.0.0.0/oracle_common/jdk/jre/bin/java -classpath /u01/app/middleware/agent_13.2.0.0.0/oui/modules/OraInstaller.jar:/u01/app/middleware/agent_13.2.0.0.0/oui/modules/emCfg.jar:/u01/app/middleware/agent_13.2.0.0.0/jlib/agentInstaller.jar oracle.sysman.agent.installer.AgentDeinstallation /u01/app/middleware/agent_13.2.0.0.0 /u01/app/middleware /u01/app/middleware/agent_inst

Manually delete the agent s/w
[oracle@uodw01 middleware]$ pwd

Now ok to install OEM agent as clean install. :)
